CBOC Lab Specimen Manifest

· Proper collection, handling, and transporting of specimens are fundamental to the quality of specimens for analytical testing in the laboratory. Transportation of samples requires compliance with federal transportation regulations.

· Discard all blood collection sharps in biohazard waste containers approved for sharps disposal.

· Transferring a sample collected using a syringe to a tube is not recommended. Additional manipulation of sharps increases the potential for needlestick injury.

· Take precautions to protect against exposure to aerosols and splashes from open sample containers.

· Print the lab orders to be collected from CPRS. The printed orders specify the sample and tube type for collection.

· Not all tests can be shipped due to sample stability limitations.

· Contact Pathology & Laboratory Medicine service 7 days/week, 24 hours/day at ext. 2383 for clarification on collection instructions.

· Whenever possible, have the patient state his identifiers: “Please tell me your date of birth.” Do not ask a ‘yes’ or ‘no’ question like, “Is your birthday May 7th?”

· Allow tubes to fill until the vacuum is exhausted to ensure the proper blood-to-additive ratio.

· Overfilling or under-filling of tubes will result in an incorrect blood-to-additive ratio and may lead to incorrect analytical results.

· Correctly labeled specimens contain the following information:

a. Patient’s full name

b. Full SSN

c. Collection date and time (use military time)

d. Collector’s initials

· Place the label lengthwise on the tube just below the cap. The label must not overlap itself, protrude from the sides, extend onto the tube cap/stopper or obscure the view of the specimen inside the tube.

· It is acceptable to trim the end of the label. However, do not remove any patient ID or collection date/time information.

· Allow Tubes for Serum to Clot

a. Tubes for serum like the Gold or Red top contain no anticoagulant and are intended to clot completely before being centrifuged.

b. Separation of serum from cells should take place within 1 hour of collection.

c. Allow blood Vacutainer tubes for Serum to clot thoroughly before centrifugation. BD recommends the following clotting times:

· 60 minutes for Red Top tube (no gel separator)

· 30 minutes for Gold Top (BD SST) tube

d. Patients with abnormal clotting times due to disease or anticoagulant therapy require more time for complete clot formation.

· Tubes for Plasma like the light green top Lithium Heparin gel-separator tube do not need to sit for any period of time before centrifugation. These tubes are not intended to clot.

· Centrifuge to Separate Plasma/Serum from Red Blood Cells

a. Balance tubes in the centrifuge. Match tubes of the same fill level and make sure that tubes are properly seated.

b. Spin gel tubes at 1100 – 1300 RCF (g) for 15 minutes if using a fixed angle centrifuge or 10 minutes if using a swing rotor centrifuge.

c. Spin all non-gel tubes at less than or equal to 1300 RCF (g) for 10 minutes.

d. Allow centrifuge to come to a complete stop before attempting to remove tubes.

· Important Note: Do not re-centrifuge gel separator tubes. Aspirate serum or plasma from the tube and place in a clean test tube to re-centrifuge.

Transfer Sample to Transport Tube

· After centrifuging, carefully remove tube stoppers to prevent aerosolization. Gauze or a stopper removal device may be used.

· Transfer serum or plasma to a plastic transport tube using a polyethylene transfer pipette. Do not aspirate any of the red cells into the pipette.

· Securely fix lid on transport tube to prevent leakage.

· Label all tubes with the patient’s full name, full social security number, date and time of collection and initials of collector.

· Mark transport tubes to indicate sample type.

a. Mark Plasma tubes with a green marker on the lid and label.

b. If the sample is from a tube other than a Green or Gold top, write the tube type on the label. For example, “Plain Red”, “Dark Green”

· Refrigerate separated samples until just prior to packing the shipping box.

· CBC (Hemogram & Five-Part Diff)

· HGB & HCT only

· Reticulocyte count

· Hemoglobin A1C

· RBC Folate

· These tests are performed on whole blood only

Samples for Prothrombin Time

(PT) & INR

· Prothrombin Time (PT) & INR specimens can be shipped to the Raymond G. Murphy Medical Center Laboratory for testing with the following restrictions:

a. Specimens must be maintained at room temperature (15-30C)

b. Testing must occur within 24 hours of collection

· Collection Instructions

a. Collect in a light blue top tube (3.2% sodium citrate additive)

b. Gently mix immediately after collection to help prevent clotting

c. Tube must be filled within 10% of the marked draw volume of the tube to ensure the right blood to anticoagulant ratio

d. If using a butterfly collection kit, use a waste tube to clear the excess air from the device tubing

· Handling & Storage Instructions

a. Tube must remain unopened

b. Do not centrifuge tube

c. Do not store in the refrigerator. Do not ship with frozen gel ice pack.

d. Specimen is stable for 24 hours at room temperature

· Rejection Conditions

a. PT & INR testing cannot be performed on specimens that are improperly labeled, hemolyzed, clotted, underfilled, overfilled, or collected in the wrong tube.

b. Specimens will be rejected if the correct shipping temperature was not maintained or if the specimen was shipped with ice.

c. Tests other than PT/INR (e.g. PTT) cannot be performed

· Shipping Instructions: See the Packing Samples for Shipment section of this document for detailed instructions on shipping room temperature specimens.

Urine Samples

· Random Urine Collections:

a. Instruct the patient to collect the urine into a sample cup labeled with their ID information.

b. Transfer the urine to the appropriate transport tube using a polyethylene transfer pipette or BD urine transfer device (straw).

· Preserving Urines for Shipping

a. Ship urine samples in the appropriate preservative transport tube.

b. Label tubes with the patient’s full name, full social security number, and date and time of collection.

c. Refrigerate all urines until just prior to packing the shipping box

Documents to Include:

Test Orders and Packing List

· Each shipping container must include a specimen manifest and printed test requisitions for the enclosed specimens.

· A manifest is a packing list of all the specimens in the container to be shipped. It is an inventory of the actual contents of the box that is used to ensure all specimens that were shipped have been accounted for when the container arrives in lab.

· Place specimens in plastic biohazard bag.

· Specimens from different patients must be placed in separate bags.

· One patient per bag

· Place the printed requisition in the outer pocket of the biohazard bag, separate from the specimens. Alternatively, requisitions can be placed in an envelope between the inner Styrofoam liner and outer cardboard of the shipping box.

Packing Specimens for Shipment:

Refrigerated

· Refrigerated Specimens (temperature range 2-8C)

· Ship with frozen gel packs to ensure temperature refrigerated temperature is maintained. Freeze gel pack overnight before use.

· Additional frozen gel ice packs may be required in warmer months to maintain specimen integrity during transport.

· Do not allow specimens to come into direct contact with frozen gel ice packs. Use a plastic canister, paper toweling or other material to separate.

Packing & Labeling the Shipping Container – Refrigerated Specimens

· The manifest should match the contents of the box exactly.

· Do not indicate samples on the manifest that will not be shipped.

A label reading “UN3373 Biological Substance Category B” should be clearly visible indicating that the box contains samples for diagnostic testing.

Packing Specimens for Shipment:

Room Temperature

· Room Temperature Specimens (temperature range 15-30C)
